Yeah, great job!

I don't think so. Paraphrasing from Paul Maley's 'resume' for Eurosom 2:

'During the first earth flyby of the Galileo spacecraft Paul Maley 
established a new long distance record for observation of a man-made object 
 --- 600,000km which was done with an 81 cm reflecting telescope. 
The observation was mentioned briefly in a news note in SKY AND 
TELESCOPE magazine.'
